Bumping this thread to say what a blast I'm having with Skyrim after getting it all modded up. My first play-through I felt a little meh about it: beautiful scenery, lame world. The expectation as always with these games is let the modders do their thing. Playing Skyrim again two years later really validates that.
It takes a pretty significant investment of time to get everything installed, the data files cleaned, the load order right, etc. But the result is well worth it. The added immersion from mods like SkyTEST, Immersive weapons/armors, Immersive Patrols, Frostfall, Wet & Cold, etc., is awesome. Here is my current mod list for anyone who is interested. This is stable and performs well on my i7-3770 w/16GB and a GTX660, although I am pretty sure I am right on the edge of Papyrus not being able to run all the scripts without lag.
